Description

Method and device to control a motor of an existing vehicle
Description 5
Field of the invention
The invention relates to a method to control a motor of an existing vehicle, said vehicle being provided with a motor management system and an On Board Diagnosis system. Furthermore, the invention relates to a device that can be 10 retrofitted into an existing vehicle to control a motor of said vehicle.
Background of the invention
Ineffective use of a motor of a vehicle has many drawbacks. For example, an idling motor, for example during waiting for a traffic light or in a traffic jam, consumes fuel, 15 emits toxic exhaust components, and contributes to the formation of smog, which can be avoided by stopping the motor. By enabling specific control of the motor, this ineffective use of fuel or electric energy can be prevented. However, modern existing motor vehicles are provided with a motor management system already controlling the motor. It is therefore required that an auxiliary method to specifically 20 control the motor, as mentioned above, is compatible with this motor management system.
The methods to control a vehicle motor described in GB 2427655, US6532926 and US7083020 are developed to be implemented in the motor management system by 25 the original vehicle manufacturer (OEM). Devices performing the steps of these known methods can not be retrofitted in an existing vehicle. One system that can be retrofitted independently of the motor management system is described in US 20100131152. In this system controlling the motor results in stopping the motor and turning off other components of the vehicle. To solve problems arising from turning 30 off other components, this system comprises bulky and expensive components. For an user that is interesting in the saving aspects of a retrofit motor control system, this is not attractive.
1039142 2
Many methods to control a vehicle motor, that are implemented in the motor management system, function automatically, which means that when a vehicle is standing still and the motor is idling, for example while waiting for traffic signals to 5 change, the motor will be stopped automatically, without the intention of the driver. Only few known methods to control a vehicle motor function non-automatically and can be activated by the driver.
In GB 2427655 a motor vehicle is described having a motor stop-start system that 10 can be turned on and off by the driver by operating a switch. The driver can not control the use of the start-stop system while remaining his of her hands on the steering wheel. The system, in its operative state, stops and restarts automatically.
For a method to be compatible with the motor management system of the vehicle it 15 is required to communicate with this motor management system. However, the only interface that is able to communicate with the motor management system is an On Board Diagnosis (OBD) system. The OBD-II standard has been mandatory for all cars and light trucks sold in the United States since 1996, and the EOBD standard has been mandatory for all petrol vehicles sold in the European Union since 2001 20 and all diesel vehicles since 2004. The OBD system is for the technician to down load Diagnostic Trouble Codes (DTC) which facilitates the trouble shooting process during a service. A method to control the motor of an existing vehicle, that is, independent from its motor management system, will each time result in a Diagnostic Trouble Code and consequently in a malfunction indicator light on the 25 dashboard indicating a problem, for example “Check Motor”. Furthermore, regularly use of the auxiliary motor control system will result in a vast amount of Diagnostic Trouble Codes stored on the storage medium of the OBD system which will impede the technician during his maintenance service.
30 While many manufacturers focus on the development of new unique motor management systems, it remains useful to develop methods and devices for existing vehicles.
3
Therefore, it is an object of the invention to provide a method to control a motor of a vehicle, said vehicle being provided with a motor management system and an On Board Diagnosis system, to increase efficient use of electrical energy and/or fuel. 5 Preferably, the driver is able to initiate this control method intentionally while remaining his or her hands on the wheel. Furthermore it is an object of the invention to provide a device to perform the steps of the method described above, which is cost effective and straightforward to be retrofitted in an existing vehicle.
10 Summary of the invention
The present invention provides a method to control a motor of an existing vehicle, said vehicle being provided with a motor management system and an On Board Diagnosis system, comprising the steps of, a) receiving at least one input signal from at least one component of the vehicle, b) determining if said at least one input 15 signal of step a) represents at least one specific condition required to control the motor, c) generating at least one output signal to control the motor, d) receiving at least one input signal from the On Board Diagnosis (OBD) system, e) determining if said at least one input signal of step d) represents a Diagnosis Trouble code, and f) generating at least one output signal able to reset said Diagnosis Trouble Code.
20
This method is able to control a motor of an existing vehicle such that, in specific conditions, it circumvents the motor management system of said existing vehicle. Furthermore, regular use of this method will not result in a vast amount of Diagnostic Trouble Codes stored on the storage medium of the OBD system which 25 will impede the technician during his maintenance service.
Preferably, the at least one output signal is generated before the On Board Diagnosis system generates an indicator signal. The advantage of such a method is that a motor of an existing vehicle can be controlled without the On Board Diagnosis 30 system alarming the driver each time the method is performed.
4
As used herein, the term “motor” refers to the motive power source of a motor vehicle that may be a gasoline engine, a diesel engine, an electric motor or other power source.
5 As used herein, the term “On Board Diagnosis” or “OBD” system refers to a On Board Diagnosis system that is used in existing vehicles. Nowadays, the standard OBD system is the OBD II system.
As used herein, the term “indicator signal” refers to a signal resulting in a indication 10 for the driver a Diagnosis Trouble Code (DTC) has been diagnosed, for example a “Check Motor Light” indicator or light on the dashboard. The DTC’s related to the motor specifically result in activation of the “MIL” (Malfunction Indicator Light) on the dashboard.
15 Step b), determining if said at least one input signal represents at least one specific condition required to control the motor, prevents a condition wherein the motor will be controlled unsuitably and a DTC will be reset unsuitably. Preferably, a plurality of specific conditions related to the vehicle are required to control the motor (see hereunder).
20
As used herein, the term “existing vehicle” refers to a vehicle that is already produced by the original equipment manufacturer (OEM), for example an aftermarket vehicle or every kind of new conventional vehicle.
25 Preferably, the at least one input signal from step d) can be all possible signals an OBD system is able to generate in relation to the motor. Preferably, the at least one output signal referred to in step f) can be all signals to enable resetting of all possible DTC’s relating to the motor.
30 One example of at least one signal to control the motor can be a signal to stop the motor by turning off the fuel pump to interrupt fuel pumping. To control the motor different components can be involved, so different signals can be generated. The 5 variety of components and signals that can be involved is dependent on the manufacturer of the vehicle and the vehicle type.
The standard OBD system, OBDII, is able to use multiple discrete communication 5 protocols dependent on the manufacturer of the vehicle. Preferably, the at least one input signal of step d) and the at least one output signal of step f) are compatible with the communication protocol used by the OBD system of said vehicle.
Preferably, a lag time is inserted between step b) and step c). Preferably, the 10 method comprises a step, between step b) and step c), of generating an audio signal to make the driver aware that the motor will be controlled. This audio signal can be generated in the beginning of this lag time.
In a preferred embodiment of the method according to the invention, the at least one 15 output signal of step c) is at least one signal to stop the motor. By stopping the motor under specific conditions electrical energy or fuel can be saved, for example while waiting for the traffic light or while waiting in a traffic jam. Stopping the motor will also help to reduce smog formation.
20 Preferably, the at least one input signal from at least one component of the vehicle of step a) is a plurality of signals representing a speed condition with a speed lower than a predetermined value, and a depressed clutch pedal condition. Preferably, the vehicle speed is zero.
25 By depressing the clutch pedal while having a low speed or while decreasing the speed, the driver is able to intentionally control the motor via the method according to the invention. Therefore, the driver should adjust its driving behaviour to specifically control the motor. On the other hand, he or she can maintain his or her hands on the steering wheel.
Furthermore, it is preferred that this plurality of signals further represent a signal selected from the group consisting of at least one signal representing a non-reverse 30 6 gear condition, at least one signal representing a condition of a motor temperature being higher than a predetermined value, and at least one signal representing a battery charge being higher than a predetermined value. The requirement of the non-reverse gear condition prevents the motor from being stopped via the method of 5 the invention while the driver is planning to drive backwardly. The requirement of the condition of a motor temperature being higher than a predetermined value prevents the motor from being stopped while the motor is still (too) cold and perhaps relatively difficult to restart. The requirement of the condition of a battery charge being higher than a predetermined value prevents the motor from being stopped 10 while battery charge is too low to maintain the functions of the heating, air conditioning, lights, etc. or even too low to restart the motor. Preferably, the method comprises the step of generating a warning signal for restarting the motor, after step f), in a condition the battery charge becomes lower than a predetermined value due to functioning of other components while the motor being turned off. Furthermore, it 15 is preferred that the at least one input signal referred to in step a) is one signal or a plurality of signals that can be expected.
In yet another preferred embodiment of the method according to the invention, the at least one input signal from at least one component of the vehicle of step a) is a 20 predetermined amount of signals each representing a covered distance condition, whereby the total amount of signals represent a distance that is higher than a predetermined value. This method applies to the situation the motor has been started recently after a stop and has covered a low distance. This condition required to stop the motor is to prevent the motor from being stopped in a situation that the 25 distance covered after the vehicle stood still is very small. For example, when the driver is crossing a roundabout point. Each one of the predetermined amount of signals represents a single distance. The predetermined amount is dependent on the distance each one of the signals is representing, which is again dependent on the manufacturer of the vehicle and the vehicle type. For example, a signal 30 representing a distance condition originates from a gear box or ABS related sensor.
7
In yet another preferred embodiment of the method according to the invention, it further comprises the steps of, g) receiving at least one input signal from at least one component of the vehicle, h) determining if said at least one input signal of step g) represents at least one specific condition required to start the motor, and i) 5 generating at least one output signal to start the motor. The steps g) - i) are performed after the motor has been stopped via the method according to this invention. The difference between the at least one input signal from at least one component of the vehicle referred to in step a) and referred to in step g) is that the signal referred to in step a) is a signal of a component of the vehicle in a condition 10 the motor of the vehicle has not been stopped via the method according to the invention, and the signal referred to in step g) is a signal of a component of the vehicle in a condition wherein the motor of the vehicle has been stopped via the method according to the invention. This method not only controls the motor by stopping it under specific conditions but also by starting the motor under specific 15 conditions.
Preferably, the at least one input signal from at least one component of the vehicle of step g) is at least one signal representing at least two consecutive short depressed brake pedal conditions. Preferably, the short depressed brake pedal 20 conditions last for a maximum of 2 seconds, more preferably for a maximum of 1 second.
One of the advantages of the at least one output signal of step c) to start the motor being at least one signal representing at least two consecutive short depressed 25 brake pedal, is that the driver, again intentionally, can start the motor while maintaining his or her hands on the steering wheel.
In another preferred embodiment of the method according to the invention, it further comprises the steps of j) varying the at least one output signal to start the motor 30 referred to in i); k) determining the resulting length of the time period during which the start motor is activated, and I) deducing an optimum time period during which the start motor is activated. Using a method to control the motor according to the 8 invention, as described above, results in regular activation of the start motor. Consequently, the performance of a start motor may decrease. By determining an optimum time period during which the start motor is activated, and consequently applying said time period, a decreasing performance of the start motor due to 5 regular use is prevented or delayed. Furthermore, by applying said deduced time period to start the motor, the start motor is used more efficiently saving electrical energy and/or fuel.
The present invention further provides a device that can be retrofitted into an 10 existing vehicle to control a motor of said vehicle, said device being configured to perform any one of the methods described above. The device according to the invention consists of hardware, having a housing and specific connectors, see below, and a processing system. The device comprises a program comprising software code portions for performing any one of the methods described above, 15 when the program is run on the processing system.
In a preferred embodiment of the device according to the invention, it comprises a DB9 connector pinout and is configured to use at least one communication protocol of a standard OBD. The OBD connector can be plugged into the Data Link 20 Connector (DLC) of the OBD. Conventionally, this cable is meant to be used by a technician in a service centre to read out the DTC’s during service. The technician uses some sort of hardware interface reading the DTC's and, after fixing the problem, resetting them. The basic of said DB9 connector pinout and the OBD connector pin out is known by the person skilled in the field of automotive 25 technology.
Using the DB9 connector pinout a standard OBD cable having an OBD connector on one end and a DB9 female serial connector on the other end can be used to transmit the DTC and DTC resetting signals from and to an OBD. That is, the at 30 least one input signal from the On Board Diagnosis (OBD) system of step d) can be received via the OBD cable. The at least one output signal able to reset said Diagnosis Trouble Code of step f) can be transmitted via the OBD cable to the OBD
9 system. The OBD cable is useful for receiving and transmitting the signals mentioned above.
One pin of the DB9 connector pinout, battery power, can be used to monitor the 5 battery charge, for example to give a warning signal preventing the battery charge will become too low to start the motor. A battery charge being higher than a predetermined value can be a required condition of the battery (a component of the vehicle) to stop the motor in a method described above.
10 Preferably, the device according to the invention is configured to, upon connecting the system of the invention to the OBD port of the existing vehicle, determine the communication protocol of said particular port.
Retrofitting such a device comprises the steps of connecting said system to the 15 OBD system present in the existing vehicle by using a standard OBD cable having an OBD connector on one end and a DB9 female serial connector on the other, and electrically connecting the system to at least one component of the vehicle.
By unplugging this standard OBD cable the user is able to remove or disable the 20 device according to the invention.
In yet another preferred embodiment of the device according to the invention, it comprises a 16 pole connector to enable an electrical connection to at least one component of the vehicle. Preferably, the 16 pole is enabling an electrical 25 connection to a personal computer, or to at least one component of the vehicle selected from the group consisting of a battery, a motor start relay, a motor stop relay, a dynamo, a start motor relay, an ABS sensor, a gearbox sensor, a motor temperature sensor, a brake pedal switch or a clutch pedal switch.
30 Preferably, the at least one input signal of step a) can be received via a wired connection between the 16 pole connector and at least one vehicle component.
Preferably, the at least one output signal of step c) that is generated, can be 10 transmitted via a wired connection between the 16 pole connector and at least one component of the vehicle.
It is preferred that the device according the invention comprises a serial 5 communication connection to enable a connection to a computer or another electronic device. Additionally, the serial communication connection can be integrated into the dash board of the vehicle. Such a connection enables communication with the device according to the invention using a computer, for example to monitor the driving behaviour of the driver.
10
Furthermore, it is preferred that the device according the invention comprises memory means for monitoring driving behaviour of the driver of the vehicle by . storing the at least one input signal from at least one component of step a), the at least one output signal to control the motor of step c), the at least one input signal 15 from the On Board Diagnosis system of step e), and/or the at least one output signal of step f).
